Brain tumor is a primary tumor that grows in the brain. Although it can be divided into benign and malignant, it is not allowed to expand the internal volume of cranial cavity. Therefore, no matter what kind of tumor, it can directly cause local damage to brain tissue, affect cerebral blood circulation, block cerebrospinal fluid circulation, cause hydrocephalus or brain edema, and even cause cerebral hernia, threatening patients' lives. So no matter what kind of intracranial tumor it is, early diagnosis and early treatment are the most important.

The incidence of brain tumors accounts for about 1.8% of all tumors in the whole body. In children, the incidence of brain tumors is relatively high, accounting for about 7% of all tumors. In general autopsy materials, brain tumors account for about 1.3% ~ 20%.

Based on years of data, it is generally believed that there is no obvious gender difference in brain tumors. Among the 2 177 cases of brain tumors, there were 429 cases of male/kloc-0 and 728 cases of female, with more males than females. Some types of tumors may have significant differences in gender. For example, pinealomas are more common in male children.

Intracranial tumors can occur from newborns to the elderly, but they are most common in people aged 20-50. Astrocytoma, ependymoma, medulloblastoma and craniopharyngioma are more common in children before 15. Astrocytoma, pituitary adenoma, meningioma and acoustic neuroma are common in 20 ~ 40 years old. At the age of 30 ~ 50, glioblastoma multiforme and metastatic tumors are more common.

There is no clear record in ancient Chinese medicine literature, but some symptoms similar to brain tumors are mentioned sporadically. For example, there is a book entitled "The evil lies in the collaterals and the skin is unkind" in Synopsis of the Golden Chamber, "Treating Stroke with Syndrome Differentiation of Diseases and Veins"; The evil is in the meridians, and the evil is overwhelming. The evil enters the fu-organs (strange and constant fu-organs), that is, I don't know people, and the evil enters the dirty, and my tongue is hard to speak. "Uncle Ling?" Syncope "has" real headache, severe headache, brain pain, cold hands and feet to joints; Go to hell. ""rebellion "and" head wind " Symptoms of brain tumor, such as headache, vomiting, madness, epilepsy, excessive phlegm, drinking, stroke, etc. It was recorded in the later TCM literature, but some of them were not all brain tumors.

Traditional Chinese medicine believes that "evil combined with qi deficiency", tumor is caused by weak vital qi, and brain tumor is also caused by "deficiency of vital qi, evil entering", imbalance of yin and yang, cold and heat fighting, accumulation of poison in viscera, and blood stasis in camp and guard. The head is the meeting of all yang, and the three yang meridians of the hands and feet meet at the head, which belongs to yang. For the marrow sea, the strange and unchanging fu-organs are yin. Under normal circumstances, Yin Pingyang is hidden and evil can't enter. The qi of clearing yang rises, the qi of turbid yin falls, and it is healthy and disease-free Internal injuries, seven emotions, depression and rage, mental disorders, overwork, long and difficult to heal. Exogenous six evils, cold and dampness blocking collaterals, lead to stagnation of qi and blood, weakness of vital qi, and the invasion of evil spirits, which leads to the inability of clearing yang and descending turbid qi, which is confined to the brain of strange and constant fu organs, swelling and accumulation, and occurs as a brain tumor. The brain controls the whole body. Brain tumors can affect the five senses and limbs, causing them to have various symptoms, which are more closely related to the heart, liver and kidney, such as the heart governing the gods and storing essence for the gods. When brain tumor occurs, blood stasis and spleen and kidney yang deficiency lead to stagnation of phlegm and dampness, coma, headache and coma, incoherent speech and mania. Pathogenic factors suppress the heart yang, resulting in headache, facial paralysis and limb paralysis due to chest tightness, fever, dizziness and vomiting, qi stagnation and blood stasis. Liver stores blood, which can enlighten and improve eyesight. When brain tumor occurs, liver yin deficiency and liver yang hyperactivity can lead to headache, dizziness, tinnitus, deafness and decreased vision. Liver blood deficiency, on the other hand, felt stiff muscles, numbness of limbs, liver wind moving, dizziness and fatigue, and severe neck cramps, mouth and eyes askew, language difficulties and hemiplegia.
